Invalid NAL unit size in h264 encoded video
8 décembre 2022, par user2934303I have a partially damaged h264 video with several damaged frames, I tried several repair software but none managed to help with it.


I'm not sure if this is a recoverable damage to begin with, but ffmpeg gives this output when trying to decode it :


[h264 @ 0x558b7f88aa80] Invalid NAL unit size (28692 > 13652).
[h264 @ 0x558b7f88aa80] Error splitting the input into NAL units.
[h264 @ 0x558b7f88aa80] Invalid NAL unit size (-1459122140 > 102110).



Is anything that can be done about this, to try and recover the bad frames ?


Thanks !

21 novembre 2022, par Devin DixonI am grabbing a stream from X11 and streaming it to other sources like Node Media Server and Twitch. Except, I get audio only with no video and the resolution size says 0X0.


My ffmpeg is command is this :

I've noticed there are several errors the headers going out. For VAAPI, how do I set resolution header ?
